SAFETY LOCK FOR FEREARMS.

s nnorslosrron forming part of Letters Patent No. 741,754, dated October 20, 1903.

Application filed January 19,1903. Serial No. 139,534. (No model) To all whom'it may concern:

Be it known that I, .MARTIN VAN Bonnn ALLEN, a citizen of the United States, residing at New York, in the county of New York and State of New York, have invented certain new and useful Improvements in Looks for Firearms, of which the following is a specification, such as will enable those skilled in theart to which it appertains to make and use the same.

The object of this invention is provide a lock for the hammer of firearms whereby the operation of the hammer is prevented and" whereby the accidental discharge of the weapon will be avoided, a further object being to provide a device of this class bymeans of which a revolver or similar firearm cannot be operated except by a party acquainted with the construction and operation of the lock; and with these and other objects in view the invention consists in a lock of the class specilied constructed as hereinafter described and claimedi The invention is fully disclosed in the following specification, of which the accompanying drawings form a part, in which the sepa-' rate parts of my'improvement are designated by suitable reference characters in each of the views, and in which-- Figure l is a side view of an ordinary revolver provided with my improved lock; Fig;

' 2, a similar view of the breech portion of the handle removed; Fig. '3,

- volver provided with revolver with one of the side plates of the a central longitudinal section through the handle portion of the revolver; Fig. 4, a transverse section, one of the parts being in a position different from that shown in Fig. 3 Fig. 5, an inside view of one of the two frame-plates which I employ, said plates being placed within the handle port-ion of the revolver.

In the drawings forming part of this specification I have shown at a an ordinary rethe nsi1al hamrne1' I), having the usual thumb or finger'piece Z2 and the backwardly-d-irected portion b adapted. to move in a slot b in the frame a of the revolver. The hammer b is pivoted at b in the usual manner, and connected with the heel portion 12 thereof is the usual spring I)",

' which is connected a all of these parts being of the usual form and construction. I

The backwardly-directed portion b of the hammer l is provided with a slot b and the handle portion of the revolver comprises the usual metal frame 0 and side pieces or plates 0 Within the handle portion of the revolver are placed two frame-plates d and d these plates being provided at or near their opposite ends with lugs or projections (1 which are set into the frame portion 0 of the handle of the revolver, and between these plates is a space or chamber e, in which is placed a slide f, the forward end of which projects upwardly through a longitudinal slot or opening f in the top of the frame portion 0 of the handle'and provides a knob f with forwardly-directed lockplaie f the forward end of which is adapted to enter the slot or recess 12 in the backwardly-directed portion b of the hammer b, and secured to the forward end of the slide f is a spring f which is secured to the handle portion 0 atf and which normally operates to draw back or retract the slide f. The plates (1 andol are each provided on the inner side thereof with longitudinally-a1" ranged tubular bearings 9, three of which 'are shown, and on the outer sides thereof with corresponding tubularbearings g and the side plates 0 0i the handle are provided with corresponding recesses g ,'in which are placed spiral springs 9 which are secured to the plates d and 01*, as shown at g in Fig. 2. The plates d and d are provided with transverse openings which correspond with the hearings g and g and in the lefthand plate and its corresponding bearings g are placed cylindrical plugs h, provided preferably with two annular grooves b and the slide f is provided with openings h which correspond with the bearings g andeg and with the corresponding openings in the plates 01 and d The slide f is also provided'with a 1ongitudinal slot h, through which is passed the screw k by which the side plates 0 and c of the handle are secured in place, and secured to the inner side of the left-hand frameplate d is a longitudinal spring wire or rod h, which fits in correspondinggrooves in the I top of the tubular bearings g and. is adapted in Fig. 3. thereof may be pushed forward by pressing to enter the annular grooves h in the plugs h. In the left side plate 0 are placed pushbuttons i, three of which are shown in Fig. 1, and each of these push-buttons is provided with an inner flange or rim via-which fits in the corresponding recess g and each of these push-buttons is also provided with a shank 11 by means of which the corresponding plug 71. may be operated. In the right-hand side of the handle is also placed push-buttonsj, similar in all respects to the push-buttons i and provided with shanks 7' which pass inwardly through the corresponding frameplate (1, as'clearly shown in Fig. 4.

The operation will be readily-understood from the foregoing description when t en in connection with the accompanying-drawings and the following statement thereof. Suppose the parts to be in the position shown The slide f and the lock-plate f the thumb forwardly on the knob f and in this-operation the lock-platefis forced into the slot or recess" b in the hammer b, and said hammeriis prevented from operating. At the same time any one of the push-buttons i may be pressed inwardly, so as to force the correspondingplug hinwardly into one of the openings h in the slide f, and this will lock said slide in its foremost position,and the hammer I) cannot be operated until the slide f is moved backwardly, and in order to move the slide f backwardly into the positionshown in Fig. 3 the push-button j on the right-hand side of the handle corresponding with the push-button i on the left-hand side which was pushed inwardly to lock the slidef must be pushed inwardly, and in this operation the plug it will be forced back into the position shown in Fig. 4, and the springf will draw back the slide f, as will be readily understood. It will also be understood that the plug it or any one of said plugs when once operated in either direction, as above described is held in position by the spring-rod h, and said plug cannot be moved except by pressing one of the push-buttons, as hereinbefore described.

The object of employing a number of the push-buttons t' and a corresponding number of the push-buttons j is to give the lock the character of a com bination-lock, and either one or all of said push-buttons may he operated, as will be readily understood, and it will also be understood that for the purpose of simply looking the hammer only one pair of said push-buttons is necessary.

In the accompanying drawings only the plate (1 is provided with a spring locking device h for the plugs 7L, and only two of these plugs may be locked by the spring locking device It", as shown in Fig. 5, and in practice the other side plate (I is provided with a simi: lar locking device for locking the central plug it, which is placed in the right-hand side of the handloportion of the firearm; but it will be understood that various changes in the :position of said plugs and the position of the push-buttons maybe made without depart ing from the essential features of my invention, which consist of the sliding bar, the holes formed therein, the transversely-movable plugs adapted to enter said holes, and means for moving or operating said plugs.

My improved lock may also be applied to other devices or as a lock for other purposes,

and my invention is not limited to the exact construction, combination, and arrangement of the parts herein shown and described, and I reserve the right to make all such alterations therein as fairly come within the scope of my invention.

Having fully described my invention, what Iclaim as new, and desire tosecure by Letters Patent, is

1.- In a lock of the class described, a handle or frame portion, a slide mounted therein, a transversely-movable plug mounted in said handle or frame portion and adapted to be moved into an opening formed in said slide, and spring-operated push-buttons mounted in the opposite sides of the handle or frame portion and provided with shanks adapted to operate said plug, substantially as shown and described.
